Whenever my sims read a book in their house (not sure if this happens in the library, I think it doesn't) they'll leave it on the table (when they're done). When I try to put it back to the bookshelf my sim will always grab the book, sit on the closest chair (as if they were going to read it) then get up again and go to the bookshelf. I'm playing on a Mac, not using mods or CC.

I had a similar issue but mine only happens in the Library.
Both these bugs about having to sit before picking up dirty dishes and putting away books have been happening in my games for many months. And I only had the repairman mod installed but removed it months ago, after having to deal with a new patch every month. So, repair game ( for several different things) over many months and many different times doesn't fix this problem. I can't remember which patch caused these problems in my game but it was months ago. And even starting a brand new game completely patched up hasn't removed this annoyance.
I agree it's insane! I watched a Sim clear plates from a table in their garden, she picked up the plates then changed into her swimming outfit and sat down on the edge of the pool. It was only for a moment but long enough for other family members to change into swimwear and sit down next to her. And then she stood up, changed back into her everyday clothes and went inside to load the dishwasher!
